If you want to manufacture many high-end products such as drying durian, crispy drying avocado, fish, and meat…that do not change the shape and color of raw material, you can choose the freeze-drying machine. In this post, we learn about the MST500 freeze dryer with a capacity of 50kg.
You can see more another freeze dryer in the table below
| MODEL | Input Capacity |
| MST30GD freeze dryer | ≤ 3kg |
| MST50GD freeze dryer | ≤ 5kg |
| MST100 freeze dryer | ≤ 10kg |
| MST150 freeze dryer | ≤ 15kg |
| MST200 freeze dryer | ≤ 20kg |
| MST300 freeze dryer | ≤ 30kg |
| MST500 freeze dryer | ≤ 50kg |
Main components of the MST500 freeze dryer
Each MST500 freeze dryer consists of a shelf, trays, vapor condenser, refrigeration system, vacuum system, heating system, and control system. All of the components have been manufactured and installed at the Mactech factory in Ha Noi, Vietnam, making them ready for usage by clients without the need for extra installation services. Watch the video below to learn more about the freeze dryer.
Below is the location of the main parts of the 50kg sublimation dryer that we can see from the outside of the machine. All machine systems are protected by the outer frame.
Application of the MST500 Freeze dryer
When we mention the application of freeze drying machine, maybe the products can dry by freeze dryer are everything. But you have to choose the things of high value, such as durian, avocado, strawberry, mango, lotus tea, probiotics, meat, fish, and shrimp,…because these products can help you to earn suitable profit.
For crispy drying of all ripe fruits, including durian, dragon fruit, pineapple, banana, jackfruit, ripe mango, melon, and avocado, we should use a freeze drying machine. Due to the fact that freeze-dried foods maintain their original texture, color, flavor, and nutritional value, they are always expensive on the market.
The under picture describes some fully drying vegetables consist of tomato and bitter melon…that keeping original shape and color. Their structure is very crispy, and spongy, to be broken easily.
